Personal computing might soon become a far more hands-on experience. Researchers are building sophisticated touch-screen interfaces that make a mouse and keyboard unnecessary. Instead users move or stretch their fingertips to manipulate information.
The best way to understand the technology is to see it in action—for example, in a video demonstration by Jeff Han, a research scientist at New York University’s Courant Institute of Mathematical Sciences (above). He gave the presentation at a recent Technology Entertainment Design conference, in Monterey, Calif. Conference organizers placed video from the conference online. —Jeffrey R. Young
